Short Series – Metric | Kennedy KC3 throwaway 3* flute endmills are manufactured HSS-Co 5% making them much tougher than HSS. This means that Kennedy endmills can be used at higher speeds and feeds which in turn gives greater productivity. | | Suitable for slot drilling and end milling. Cutters are held in adaptors/chucks by the action of a set screw which locates on the shank flat giving quick and easy cutter change. | *Except: 1mm cutters, 2mm and 1/16″ ball nose cutters all of which have two flutes. | Shank Diameter: 1.00 ~ 6.00 = 6.00mm, 7.00 ~ 10.00 = 10.00mm | | Metric Tolerances: | Diameter: Over 1.00 ~ up to 3.00. Tolerance: +0.013, -0.033. | Diameter: Over 3.00 ~ up to 6.00. Tolerance: +0.020, -0.020. | | Kennedy KC3 endmills are available uncoated, TiN coated and TiCN coated. | | TiN (Titanium nitride) provides a surface hardness in the region of 2300HV which offers improved wear resistance, tool life and productivity. | | TiCN (Titanium Carbonitride) gives a surface hardness in the region of 3000-3500 HV, excellent wear resistance and good heat resistance. This coating is used for the same things as TiN but also for hard steels, stainless, cast iron, brass & bronze.
